Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.If there is a decrease in the RKE operating range,
try this:
Check the distance. The transmitter may be too far
from the vehicle. Stand closer during rainy or snowy
weather.
Check the location. Other vehicles or objects may be
blocking the signal. Take a few steps to the left or
right, hold the transmitter higher, and try again.
Check the transmitter’s battery. See “Battery

Each RKE transmitter is coded to prevent another
transmitter from unlocking your vehicle. If a transmitter is
lost or stolen, a replacement can be purchased through
your dealer/retailer. All transmitters need to be re-coded
to match the new transmitter. The lost transmitter will no
longer work after the new transmitters are re-coded.
The vehicle can have a maximum of eight transmitters
matched to it. See “Relearn Remote Key” underDIC
Operation and Displays (With DIC Buttons) on page 3-51
orDIC Operation and Displays (Without DIC Buttons)
on page 3-56for instructions on how to match RKE
transmitters to your vehicle.

REMOTE KEY message displays in the DIC. See
“REPLACE BATTERY IN REMOTE KEY” underDIC
Warnings and Messages on page 3-59for additional
information.

Headphones
The RSE includes two 2-channel wireless headphones
that are dedicated to this system. Channel 1 is dedicated
to the DVD player, while Channel 2 is dedicated to RSA
selections. These headphones are used to listen to
media such as CDs, DVDs, MP3s, DVDAs, radio, any
auxiliary source connected to A/V jacks, or the auxiliary
input jack, if the vehicle has this feature. The wireless
headphones have an On/Off button, channel 1/2 switch,
and a volume control.
If the vehicle has a third row video screen display, it has
two additional headphones.Push the power button to turn on the headphones.
An indicator light located on the headphones comes on.
If the light comes on but there is intermittent sound and/or
static on the headphones, or if the indicator light does not
come on, the batteries might need to be replaced. See
“Battery Replacement” later in this section for more
information. Switch the headphones to Off when not
in use.
Infrared transmitters are located at the rear of
the RSE overhead console. The headphones shut off
automatically to save the battery power if the RSE system
and RSA are shut off or if the headphones are out of
range of the transmitters for more than three minutes.
If you move too far forward or step out of the vehicle,
the headphones lose the audio signal.
The headphones automatically turn off after four hours
of continuous use.
To adjust the volume on the headphones, use the
volume control located on the right side.
For optimal audio performance, the headphones must
be worn correctly. The symbol L (Left) appears on
the upper left side, above the ear pad and should be
positioned on the left ear. The symbol R (Right) appears
on the upper right side, above the ear pad and should
be positioned on the right ear.

Notice:Do not store the headphones in heat or
direct sunlight. This could damage the headphones
and repairs will not be covered by your warranty.
Storage in extreme cold can weaken the batteries.
Keep the headphones stored in a cool, dry place.
If the foam ear pads attached to the headphones
become worn or damaged, the pads can be replaced
separately from the headphone set. See your
dealer/retailer for more information.
Battery Replacement
To change the batteries on the headphones, do the
following:
1. Turn the screw to loosen the battery door located
on the left side of the headphones. Slide the
battery door open.
2. Replace the two batteries in the compartment.
Make sure that they are installed correctly, using the
diagram on the inside of the battery compartment.
3. Replace the battery door and tighten the
door screw.
If the headphones are to be stored for a long period of
time, remove the batteries and keep them in a cool,
dry place.
Audio/Video (A/V) Jacks
The A/V jacks, located on the rear of the oor console,
allow audio or video signals to be connected from
an auxiliary device such as a camcorder or a video
game unit to the RSE system. Adapter connectors
or cables (not included) might be required to connect
the auxiliary device to the A/V jacks. Refer to the
manufacturer’s instructions for proper usage.
The A/V jacks are color coded to match typical home
entertainment system equipment. The yellow jack (A) is
for the video input. The white jack (B) is for the left
audio input. The red jack (C) is for the right audio input.
Power for auxiliary devices is not supplied by the
radio system.

Video Screen
The video screen is located in the overhead console.
To use the video screen, do the following:
1. Push the release button located on the overhead
console.
2. Move the screen to the desired position.
When the video screen is not in use, push it up into its
locked position.
If a DVD is playing and the screen is raised to its locked
position, the screen remains on, this is normal, and
the DVD continues to play through the previous audio
source. Use the remote control power button or eject the
disc to turn off the screen.
The overhead console contains the infrared transmitters
for the wireless headphones and the infrared receivers
for the remote control. They are located at the rear
of the console.
Notice:Avoid directly touching the video screen,
as damage may occur. See “Cleaning the Video
Screen” later in this section for more information.
Remote Control
To use the remote control, aim it at the transmitter
window at the rear of the overhead console and press
the desired button. Direct sunlight or very bright light
could affect the ability of the RSE transmitter to receive
signals from the remote control. If the remote control
does not seem to be working, the batteries might need
to be replaced. See “Battery Replacement” later in
this section. Objects blocking the line of sight could
also affect the function of the remote control.
If a CD or DVD is in the Radio DVD slot, the remote
control power button can be used to turn on the video
screen display and start the disc. The radio can also
turn on the video screen display. SeeRadio(s) (MP3)
on page 3-78for more information.
Notice:Storing the remote control in a hot area or
in direct sunlight can damage it, and the repairs
will not be covered by your warranty. Storage
in extreme cold can weaken the batteries. Keep
the remote control stored in a cool, dry place.
